3. Install EtherCalc

NOTE: If using Vagrant, below is an example of how to set port forwarding in Vagrantfile:

config.vm.network "forwarded_port", guest: 8000, host: 8000

4. (Optional) Install Redis

Redis is an open source software which is used for advanced key-value cache and store. It is often referred to as a data structure server. If we running Redis server in our system, EtherCalc will prefer it over file-based storage to improve performance.

I believe the only way you can have EtherCalc display on a specific page is thru an iframe – which does not seem ideal. Instead, you would just have to provide the link to EtherCalc within a website page that will start a new instance – just like what you see at the EtherCalc homepage here: https://ethercalc.net/
